number of identical characters are repeatedly encoded into different encoding codes, so that the old and complicated encoding methods can be directly converted to Unicode encoding without losing any information [1].Implementation Method The Unicode encoding of a character is definite, but in the actual transmission process, because the design of different system platforms is not necessarily consistent, and for the purpose of saving space, unicode encoding is implemented in different ways.

have a two-byte header after a byte-----------------------------The recommended method for labeling byte order in the Unicode specification is the BOM. The BOM is not a BOM for "Bill of Material", but a byte Order Mark.(Unicode is a method of character encoding, but it is a coding scheme designed by international organizations that can accommodate all languages in the world.) The scientific name for Unicode is "Universal multiple-octet Coded Character Set", referred to as

generation, and in the face of Chinese, Arabic and other complex text, 256 characters are obviously not enough. So each country or organization has formulated the standard which conforms to own language, for example gb2312, Big5 and so on. However, the practice of setting their own standards obviously has many drawbacks, so the Unicode code specification came into being.Unicode is also a character encoding method, but it is designed by international organizations and can accommodate all languag

good, this is mainly because in our case the ASCII character set code point only one character encoding, that is, ASCII character encoding. This is not always the case in other character sets, such as the Unicode character set.The Unicode character set, which specifies the code point for every character in the world, such as the code point in the Unicode character set of the English letter A is 65 (haha, this code point is compatible with ASCII), However, 65 of the storage format has many ways:

conversion handle for use by the following two functions.(2) size_t iconv (iconv_t cd,char **inbuf,size_t *inbytesleft,char);This function reads characters from INBUF, converts them to Outbuf, Inbytesleft records the number of characters that have not yet been converted, outbytesleft the remaining space to record the output buffer. (3) int iconv_close (iconv_t CD);This function closes the conversion handle and frees the resource. After testing, the following points need to be noted for using th

Does the width of more than 4 characters exist? If present, this code has a serious bug that can cause parsing to fail.Let's start with the first question:The East A

First, get the encoding format of the fileWhen we use the file input and output stream, there are often garbled problems, which is usually caused by the encoding format.To copy a document as an example:We read the file with the input stream (FileInputStream) and then re-write it to another file with the output stream (FileOutputStream).If the encoding format of the source file is inconsistent with the encoding format that we re-write, there may be garbled problems.Therefore, we need to obtain th

bytes to represent a Chinese character. Therefore, it can theoretically represent a maximum of 256x256 = 65536 characters. The issue of Chinese encoding needs to be discussed in a specific article. This note does not cover this issue. It is only pointed out that although multiple bytes are used to represent a symbol, the Chinese character encoding of the GB class has nothing to do with the Unicode and UTF-8 of the subsequent text. 3. Unicode Unicode character set (

Unicode needs to consider its encoding format has two, one is the UCS-2, it has a total of 65536 yards, the other is the UCS-4, which has 2147483648g code bit. Python supports both formats. This is specified by -- enable-Unicode = ucs2 or -- enable-Unicode = ucs4 during compilation. How can we determine the encoding of Python installed by default? One way is to judge through the value of SYS. maxunicode:

ASCII is a character set, including uppercase and lowercase English letters, numbers, and control characters. It is represented in one byte and ranges from 0 to 127. Because ASCII characters are very limited, each country or region puts forward its own character set on this basis. For example, gb2312, which is widely used in China, provides encoding for Chinese characters, it is expressed in two bytes. These character sets are incompatible with each other. The same number may indicate diff

Python's handling of multiple languages is well supported, and it can handle any character that is now encoded, and here's a deep look at Python's handling of many different languages. One thing to be clear about is that when Python is going to do the transcoding, it will use the internal code, and the conversion process is:Copy the Code code as follows: Original code, internal code, and purpose code The interior of Python is handled using Unicode, but the use of Unicode takes into account th

Php, we want to convert the uft-8 to unicode, you can use the following function to implement UTF encoding The UTF-8 is coded in 8 bits. The encoding from UCS-2 to UTF-8 is as follows: UCS-2 coding (hexadecimal) UTF-8 byte stream (binary) 0000-007F 0 xxxxxxx 0080-07FF 110 xxxxx 10 xxxxxx 0800-FFFF 1110 xxxx 10 xxxxxx 10 xxxxxx For example, the Unicode code of the Chinese character is 6C49. 6C49 is between 0
